大二暑假第一周总结
这周就开始了小学期，这周的小学期的是算法与数据结构综合训练，总共是分为两个阶段，第一阶段是基础算法训练，第二阶段是综合算法训练。
第一阶段是基础算法演示，验收的时候非常顺利，同时参与了评优，成功评上。
第二阶段我选的是导师双选系统，然后和老师所述的题目理解有相关的出入，所以老师趁着这个机会正好让我重新整理了一下我的题目的相关要求，以我的题目要求座位明年的小学期的题目之一，以至于把那些极其简单的题目替换，这些工作我是早早的完成，然后后面就是测试自己的系统，防止出现bug。
以下是我的程序的主要代码：

这周三也是端午节，也出去玩了，玩了一整天，虽说有点累，但是还是非常开心的。
这个星期不仅练习了算法编程，还复习了整个mis系统的编程。可以说是收获颇丰！
